## ویژگی های Starlette

//// tab | Python 3.9+

No Python 3.9, `Annotated` é parte da biblioteca padrão, então você pode importá-lo de `typing`.

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial013_py39.py!}
```

////

//// tab | Python 3.8+

Em versões abaixo do Python 3.9, você importa `Annotated` de `typing_extensions`.

///

## Type Hints with Metadata Annotations

Python also has a feature that allows putting **additional <abbr title="Data about the data, in this case, information about the type, e.g. a description.">metadata</abbr>** in these type hints using `Annotated`.

//// tab | Python 3.9+

In Python 3.9, `Annotated` is part of the standard library, so you can import it from `typing`.

///

## Share `Annotated` dependencies

In the examples above, you see that there's a tiny bit of **code duplication**.

When you need to use the `common_parameters()` dependency, you have to write the whole parameter with the type annotation and `Depends()`:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

## Type annotation vs `Depends`

Notice how we write `CommonQueryParams` twice in the above code:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python

        fun added(thing: String, desc: String): List<String> =
            listOf(
                "$thing ${describe(thing, desc)}: Is not annotated with @Incubating.",
                "$thing ${describe(thing, desc)}: Is not annotated with @since 2.0."
            )

        fun removed(thing: String, desc: String): Pair<String, List<String>> =

```

////

//// tab | Python 3.10+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="7  15"

```

//// tab | Python 3.8+ non-Annotated
